The ^x fullscreen viewer (OverlayDiff) backs every tool preview — split diff
for write/edit, the command card for shell, plain lines otherwise, plus any
transcript tool-output — but only scrolled one line per keypress, making a
long diff tedious to read.
- Add paging to the viewer, matching the OUTPUT free-scroll contract: ↑↓/jk
by line, PgUp/PgDn by a full body, ^u/^d by half, g/G to the ends. New
scrollDiff() clamps to [0, diffMaxScroll] so paging past either edge lands
exactly (no dead presses). diff_scroll_test.go (2): clamp + no-op-when-fits.
- Update the modal hint to advertise paging (line / page / ends / close) and
add a "diff / preview viewer (^x)" section to the ? help overlay. Also note
the T3+ confirm-again behaviour in the approval-band help.
Approval ergonomics re-audit (BACKLOG §E): the spec'd band still holds —
single-key y/n/e for T0-T2, mandatory second-key confirm for T3+ (HighTier),
navigable queue with an i/n indicator, docked band never modal-stacked; all
covered green by approval_test.go. The scroll granularity above was the only
gap, now closed.
